New York City Parks workers have covered up a statue of National Security Agency leaker Edward Snowden that was secretly installed overnight. The 100-lb bust was erected in Brooklyn’s Fort Greene Park, atop the Prison Ship Martyrs Monument.

The 4-foot tall Snowden bust was fused to the monument overnight
on Monday by a trio of anonymous artists and a few helpers,
Animal New York reported. They renamed the tribute 'Prison Ship
Martyrs Monument 2.0'.

“Fort Greene’s Prison Ship Martyrs Monument is a memorial to
American POWs who lost their lives during the Revolutionary War.
We have updated this monument to highlight those who sacrifice
their safety in the fight against modern-day tyrannies,” the
group wrote in a statement. “It would be a dishonor to those
memorialized here to not laud those who protect the ideals they
fought for, as Edward Snowden has by bringing the NSA’s
4th-Amendment-violating surveillance programs to light.

“Our goal is to bring a renewed vitality to the
space and prompt even more visitors to ponder the sacrifices made
for their freedoms. We hope this inspires them to reflect upon
the responsibility we all bear to ensure our liberties exist long
into the future.”

Most passersby didn’t notice Snowden’s head atop one of the four
columns that lie at the monument’s edge, Bucky Turco, who
exclusively documented the installation, reported.

“In fact, over a dozen people walking their dogs passed by
the new bust on Monday morning without noticing the unsanctioned
piece,” Turco wrote. “Both the color and design of the
bust expertly matches the existing sculptures there, from its
bronze patina finish to Snowden’s hair — which mimics the texture
of the feather on the eagle. The artists also added letters
spelling out Snowden’s name in an official-looking font befitting
of a monument.”

The artists told Turco that they debated how to bind the bust to
its base, eventually deciding on an adhesive that would firmly
hold the head in place, yet could be removed without damaging
Martyrs Monument '1.0'.

The idea for the sculpture was conceived about a year ago by two
New York City-based artists with a history of pulling off notable
public interventions.

“There’s a media landscape that has painted him as a
criminal,” said one of the two New York artists. “You
need something theatrical and large to counterbalance the Fox
News-iness of the texture of the conversation out there.”

They then commissioned a sympathetic West Coast artist, who took
six months to create the bust, which cost thousands of dollars
and had to be shipped across the country.

“The amount of work that goes into this kind of stuff, it’s
easily a 30 grand [$30,000] project,” said the 30-something
sculptor. “If it were bronze, it could be a $100,000 piece of
artwork, maybe more.”

The artists debated several locations, but decided on Fort Greene
because they believed it offered them the best chance to convey
the ideals that Snowden's revelations are all about. The Prison
Ship Martyrs Monument honors the 11,500 prisoners who died after
Revolutionary troops retreated during the Battle of Long Island.

“It gives the whole thing so much more meaning,” they
told Mashable. “It’s not just about Snowden. It’s about the
ideals that he was trying to work towards and push others to care
about.”

The POWs the memorial is dedicated to “were fighting for the
same ideals that Snowden is fighting for,” they added.

The New York City Parks Service removed the Snowden sign from the
monument at 11:45 a.m. ET, Mashable reported. They covered up the
bust with a blue tarp just after noon on Monday.

One of the participants told Mediaite the group would be
disappointed if the bust was taken down right away.

“But the fact that a risk was taken, the fact that image
comes out of that event that can be passed around, can never be
undone,” the artist said. “You can rip the statue out,
but you can’t erase the fact that it happened and that people are
sharing it.”
